> In this particular case shouldn't  dag run status should be failed instead of success.
> Looks like in airflow on end tasks status are checked to decide on dag run status.
> root_ids = [t.task_id for t in dag.roots]
> roots = [t for t in tis if t.task_id in root_ids]
> # if all roots finished and at least one failed, the run failed
> if (not unfinished_tasks and
>  any(r.state in (State.FAILED, State.UPSTREAM_FAILED) for r in roots)):
>  self.log.info('Marking run %s failed', self)
>  self.set_state(State.FAILED)
>  dag.handle_callback(self, success=False, reason='task_failure',
>  session=session)
